Michael Bublé Treats NYC Commuters to Impromptu Performance

New York City commuters lucky enough to be at the W. 67th Street stop on Thursday morning were treated to a sight one doesn't get to see too often (even in NYC!)--Grammy-winning vocalist Michael Bublé giving an impromptu performance right there in the tube!

Bublé sang "Who's Lovin' You" off of his new album To Be Loved, accompanied by a cappella group Naturally 7. He explained afterwards that he was elated by the experience. "Singing in the New York subway is something that's been done for years and years, and I feel like it's the most authentic, organic way to make music," he noted.

In fact, Bublé says that out of all the things he has planned to promote his new album: "This is the thing I'm most excited about." Check out his fun performance for yourself, as well as his new set—it's available now.

In another interesting note, Thursday marked the first day that wireless was made available in the NYC subway system—so we're sure plenty of fans were excited to post Bublé's surprise show as quickly as possible to their social networks.
